BRIS'I'LE-HOLDING DEVICE FOR BRUSHES AND BROOMS.

Application filed January 30, 1928. Serial No. 250,495.

This invention relates to improvements in brush and broom construction,particularly in a means for firmly holding the bristles or fiber whichforms the main body portion oi the brush, whisk broom or the like inoperative position.

An object of this invention is to provide a construction wherein thebristle or fiber portion may be clamped into position, therebyeliminating the need of sewing the folded sections of the fiber togetherin order to retain its shape and, at the same time, provide the properflare at the operating end of the brush or broom.

A further object of this invention is to provide a brush or broomconstruction wherein thedevice may be used as long as the bristle orfiber section. retains its efiiciency, which is not the case when thebristles are sewed into position, thebrush or broom, in this instance,being useful only for the time that the stitches or sewing re mainsintact.

Another object of this inventiouis to provide a broom or brushconstruction 1n which the bristles or fiber cannot become loosened anddetached from the holding member.

Other objects of this invention will appear from the following detaileddescription of the device and as disclosed in the single sheet ofdrawings, which is herewith made a part of this application.

In the drawings- 7 Figure 1 illustrates a side elevational view of thebrush or broom disclosing its members in assembled relationship.

Figure 2 illustrates a vertical sectional view of Figure 1, omitting oneof the clamping members and disclosingthe fiber or bristle portion ofthe brush in position on the retaining band and means for partly holdingthe retaining hand between the clamping members.

Figure 3 represents a sectional view of Figure 2 taken along lines 3--3.

Figure 4 illustrates a sectional view disclosing the retaining band andthe bristle and fiber portion extending therethrough, together with alooped member on the band for cooperating with a portion of the clampingmembers.

Figure 5 represents a sectional view of Figure 2 taken along line 55.

In the modification of this invention as herewith described and claimed,it is preferred that a plurality of clamping members be provided andmade of any suitable material, such as sheet metal, or the like, andformed in such a manner that portions 1 and 2 may be readily used as ahandle and sections 3 and 4 as the shank portions of the clampingmembers, which are adapted to have positioned therebetween bristle orfiber portions 5, made of any suitable material and adapted to extendthrough a properly formed retaining member 6, made of a material similarto wire and bent into a shape whereby a looped portion 7 is formedthrough which a shank or rivet 8 may extend. The fiber or bristleelement 5 comprises a plurality of strand members which are adapted tobe extended through the band member 6 in such a manner that approXimately the same amount of the fiber or bristle clement will ext-endoneach sideof the lower portion 9 of the supporting memher 6. Afterbristle or fiber portions 5 have been properly arranged in cooperationwith the supporting band (3, they are positioned between .the clampingportions 3 and 4c in such a manner that the shank member 8 of the rivetor tension element 10 passes through the loop 7 connected with the band6. Another rivet or tension element 11 is then passed through suitableopenings in the handle portions 1 and Q. The two, tension elements 10,and 11 function to bring the clamping members firmly together, therebyholding the bristles or. fiber elements 5 in fixed operable positionsothat they cannot readily become dislodged or separated from each other.

As an aid for holding the fiber strands 5 in fixed relationship to theclamping members, it is preferred that the clamping portions 3 and t beformed having downwardly extending curved edges 12 and 13 and inwardlyand downwardly protruding portions 14 and 15, which are adapted to beforced into the fiber strands when the clamping members are broughtunder tension, thereby forming an efiicient holding means for the fiberor bristle strands. In order to bring the clamping members in properalign ment and maintain them in that position under tension, it ispreferred that one of the clamping portions, including the handlesection 1 and shank portion 8, be formed having a straight edge 16,while the cooperating clamping member, comprising the handle section 2and the shank portion 4 be formed having an offset or curved section 17in which the straight edge 15 may be received and firmly held therein.

This invention provides a very efficient brush or broom in which thefiber or bristle portion comprising a plurality of strands is doubledover and positioned between two metal clamping members. The fiberstrands, being doubled over between the clamping elements, cannot becomedislodged, and the metal clamping portions are constructed in such amanner that they cannot slide sideways and the lap or inwardly extendingportion on each clamping member tends to grip the fiber so that itcannot readily be re moved, nor can the fiber extend inwardly of theclamping member owing to the manner in which the supportin band is heldbetween the clamping members by the loop and rivet shank. The deviceherewith described and claimed is practically indestructible. The shapeof the clamping members is such as to give the proper flare to thebrush, so that the need for sewing any portion of the fibers is entirelyeliminated, which tends to make this invention a useful device so longas the fiber strands last. It is well known that, in case of a sewedwhisk broom, for instance, its usefulness exists only so long as thestitches or sewing remains intact.

It is to be understood that alterations and substitutions may be made inthe embodiment of the invention as defined in the above specifications,including the drawings which are herewith made a part of thisapplication, within the scope of the appended claims without affectingthe merits of this invention.

\Vhat I claim is:

1. In a brush having folded bristles, means clamping the bristles inposition comprising a pair of clamping members, tension membersextending through the clam ing members, supporting means for the ristlesbetween the clamping members consisting of a suitably formed band memberextending through the bristle fold, means supporting the band betweenthe clamping members consisting of a loop on the band member adapted toreceive a tension element.

2. In a brush having folded bristles, means clamping the bristles inposition comprising a pair of clamping members, tension membersextending through the clamping members, supporting means for thebristles between the clamping members consisting of a suitablyformedband member extending through the bristle fold, means supportingthe band between the clamping members consisting of a loop on the bandmember adapted to receive a tension element, means for maintaining theclamping members in positive relationship to each other consisting ofsuitably formed adjacent edges, one of which overlaps the other.

3. In a brush having folded bristles, means clamping the bristles inposition comprising a pair of clamping members, tension membersextending through the clamping members, supporting means for thebristles between the clamping members consisting of a suitably formedband member extending through the bristle fold, means supporting theband between the clamping members.

consisting of a loop on the band member adapted to receive a tensionelement, means for maintaining the clamping members in positiverelationship to each other consisting of suitably formed adjacent edges,one of which overlaps the other, and inwardly extending lip portionsalong the lower edges of the clamping members for firmly gripping thebristle strands.

In testimony whereof I affix my signature.
